I have a <telerik:RadButton Enabled="false"/> disable that is enable through javascript once the 3 fields are fill with at leas 5 letters are entered. <telerik:RadTextBox runat="server" ID="txtName" onkeyup="SetButtonStatus()" /> <telerik:RadTextBox runat="server" ID="txtEmail" onkeyup="SetButtonStatus()" /> <telerik:RadTextBox ID="txtMessage" runat="server" onkeyup="SetButtonStatus()"/> The code i have works (no errors). but it doesn't submit.
